Platinum Solos are a damn good speaker but you won't get dynamics or transparency without LOTS of power. I tried them 7-8 yrs ago with a 160wt Mesa Baron P/P tube amp -worked pretty good but I could tell they could handle even more. And I second the appearance comment, still look great today and I think they are a classic (looks wise).
The Spicas like/need lots of power, too.
